Application f led May 10,1906. Serial No. 316.208.

To all whom it may concern:

Be it known that I, OHARLEs F. BARR, a citizen of the United States, residing a Winchester, in the county of Frederick and State of Virginia, have invented certain new and useful Improvements in Roller Window- Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in roller-screens for windows; and the object of the invention is to produce a simple and efficient device of this nature comprising a casing in which is mounted a spring-actuated roller upon which a screen is adapted to wind, one end of the screen being attached to a closure of the casing and adapts.

ed to be detachably held to the sash, and in the provision of means for holding the screen tightly against the parting-strip between the sash of a window-frame.

The invention consists, further, in various other details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompa-v nying drawings, in which Figure 1 is an elevation showing my screen attached to the sash of a window. Fig. 2 is a perspective view showing means for automatically holding the edge of the screen against the parting-strip. Fig. 3 is a perspective view showing the means for fastenin the screen to the sash of a window. Fig. 4 1s a sectional view showing the manner of holding the casing to the window, and Fig. 5 is a detail sectional view showing the rollers mounted upon the casing for holding the screen at all times in the same vertical plane.

Reference now being had to the details of' the drawings by letter, A designates the frame of a window, and B the sash. Said sash is guided in the usual groove in the window-frame, and O is a parting-strip dividing the two sash of the window.

D designates a casing, which may be of any desired size and shape and in which a spring-. actuated roller E is mounted. F designates a screenwhich is secured to and adapted to Wind about said roller, and one end of the screen is secured to a strip G, which forms a closure for the casing when the screen is wound up. Said strip or lid forming the closure to the casing is wider than the grooves of the window-casing in which the boX or casing is forced excepting at the ends, where it is notched or recessed away, which will allow the edges of the screen to be held adjacent to the parting-strip of the window-frame. H H designate two plates which are fastened to the ends of said casing, and I I designate staple-shaped members having two arms I and I Each end of the casing is provided with one of said staple-shaped members, which are secured to the flanged edges of said plates.

The arms of one of said staple-shaped meme bers project through the end of one of said plates and are adapted to form means where: by one end of the casing may be. fastened in the frame by engaging slots formed therein. J ournaled upon one arm of each of said stae ple-shaped members is a roller J, which is positioned adjacent to the opening H in said plate and adapted to hold the screen against the parting-strip of the window, thereby preventing the screen or netting from swaying back and forth under the influence of wind or other causes and preventing the netting or screen from becoming baggy. The opposite end of the casing from that having the arms which project through the plate is provided with a spring-pressed rod N, which passes through an aperture in the adjacent plate and is adapted to engage an indenture or hole formed in the frame of the window. Said rod has a portion N bent upon itself, forming a handle, whereby the rod may be withdrawn from engagement with the frame of the window. The strip which forms said closure is provided with transverse apertures Q for the reception of the angled latches L, the shank portions of said latches passing, preferably, entirely through the apertures provided for their reception, in which they have bearings, and each of said members L has its end bent to form a hook L, adapted to engage over a laterally-projecting angled end M of the fixed catch M, which is adapted to fasten to the bottom rail of the sash. Each of said members L has a part L bent upon itself to form a handle, whereby said member L may be swung over the angled end M of the member M or out of engagement therewith. The lower end of the member M has a hook portion M, which is adapted to form a stop to limit the swinging movement of the latch L the closure of the casing may be attached to the bottom of the sash and held securely in contact therewith, even though the pressure incident to unwinding of the screen will come upon one edge of said strip forming the closure. In order to prevent wear coming upon the sash-rail, I have provided a plate 0, adapted to hold the swinging hook L from engagement with the surface of the sash.

Fixed to the side of the window-frame is a plate Q, having its lower edge sli htly outwardly bent, forming a cam edge a, and Q designates a hook which is struck up from said plate and downwardly bent, as shown in the drawings. Q designates a pin which projects from said plate and has pivotally mounted thereon an angle-bar Q, with a roller Q journaled upon the angled end thereof. Q designates a spring fastened at one end to said plate and wound about said pin, forming a coil, and one end of the spring is bent to form a hook Q engaging over the arm of the angle-bar Q and adapted to normally hold the same in the position shown in solid lines in the drawings at right angles to the length of said plate. Said plate Q is adapted to be fastened to the window-frame in such a position that the roller will bear against the edge of the sash of the window, and when the sash is raised the spring will throw said roller against the screen as it unwinds and cause the same to be held against the parting-strip of the window-frame, thereby preventing any flapping of the screen in the event of a current of a1r coming against the same. The operation of said roller Q it will be noted, will be entirely automatic, as it will be thrown away from the parting-strip as the sash is lowered, said sash causing the bar to swing down, and as the latter comesin contact with the cam edge Q the end of the roller willbe swung out of the path of the sash in the. position shown in dotted lines in the drawings. v

From the foregoing it will be noted that by the provision of my improved roller-screen means is afforded for attaching the device to any ordinary window and so arranged that the screen may be unwound as the window is opened and the edges of the screen securely held against the parting-strip of the frame, preventing any flapping of the edges, the screen being held by means of the rollers mounted in the casin and also by the auto matically-actuated ro lers which are fixed to theframe of the window.
